Two highly relevant pieces of information that would effect my decision:
How high is the crime rate in the area?
Are you armed (and if so, to what extent)?
EDIT: Downvoters, would the fact that you are in Mission Viejo, California or Baltimore, Maryland not effect your preferred strategy or is there something else about this comment that makes it of low value?
Didn't downvote, but "stranded" makes me think 'middle of the desert' and doesn't at all make me think 'bad neighborhood', so maybe they thought your comment was non-topical.
In every single news story that I can remember about someone getting stranded with a broken-down car, the person leaves their car looking for help and they end up dead. Or, if there are multiple people in the car, the one person who goes off looking for help ends up dead and the other people who stayed with the car survive.
My question: If I get stranded in my car somewhere, should I go looking for help? Or should I follow my availability heuristic and stay put? Since I'm still in the process of debiasing myself, should I do the opposite of what this particular mental shortcut suggests, or would that be a sort of bias bias (analogous to the fallacy fallacy)?
